Volcano Activity from 1960 through 1995 (WMS)
This animation represents cumulative global volcanic activity over a 36-year span, from 1960 through 1995. Volcanoes occur near but not on tectonic plate boundaries. If a plate boundary is a convergent boundary, where one plate is subducting under another, then volcanoes occur on the top plate, over the area where rock from the subducting plate has melted, is rising, and has broken through to the surface. The Mt. St. Helens eruption is visible in this animation starting in March, 1980. Note: This animation shows cumulative global volcano activity from 1960 through 1995. The color of each dot indicates the strength of the activity of the volcano. Data Collected: 1960/01/01 - 1995/12/31. Animator: Horace Mitchell (NASA/GSFC), Eric Sokolowsky (GST). Scientist: Tom Watters (Smithsonian/Air and Space). Platforms/Sensors/Data Sets: Airborne Topographic Mapper, Global Volcanism Program.
